Abstract (en)
[origin: ES8305338A1] Herbicidally active substituted phenylsulfonyl urea derivatives of the formula < IMAGE > in which X is phenyl or phenoxy, R is < IMAGE > and R1 and R2 each independently is methyl or methoxy. They are made from phenylisocyanates of the formula -SO2-N=C=O which are produced by reacting a phenylsulfonamide of the formula < IMAGE > with phosgene or with trichloromethyl chloroformate in the presence of an aliphatic isocyanate.
